A Hand Grenade In The Shape Of A Baseball Sports Ball Manufactured During WWII By The Photography Film Manufacturer The Eastman Kodak Company; Called The BEANO T-13 Grenade.

Kodak was likely awarded the Contract by the United States Federal Government to produce these uniquely-shaped Hand Grenades likely due to Kodak’s expertise in manufacturing chemicals necessary for Photographic Films, Movie Films, and Film Development; and this expertise in manufacturing Photographic Chemicals would come in handy for manufacturing the destructive chemical contained in these BEANO T-13 Hand Grenades.
